Abstract

An air freshener device (10) having a cartridge (14) and a cartridge housing (16) is disclosed. The housing (16) has a sealed first cavity (18) and a sealed second cavity (20) having a first fragrance (22) and a second fragrance (24), respectively. First and second cavities (18) and (20) have first and second opening (34) and (54) respectively. The device (10) includes a housing (12) having air passage openings (70), (76), (78), a fan (82) and power means (80) and also supports cartridge (14). When the power means (80) powers the fan (82) the air passage openings (70), (76) and (78) receive air which moves from the second (76) to the third (78) air passage opening and from the first air passage opening (70) across the cartridge (14) picking up the fragrances (22) and (24), resulting in an air-fragrance mixture which is drawn into an unobstructed air flow between the second and third air passage openings (76) and (78) and exits the third air passage opening (78), thereby allowing dispersion of the fragrance (22) and (24).

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A cartridge for an air freshener device, comprising: (a) a housing, the housing have a sealed first cavity and a sealed second cavity;   (b) a first fragrance located within the first cavity, the first fragrance having a first volatility;   (c) a second fragrance located within the second cavity, the second fragrance having a second volatility;   (d) the first cavity having a first opening therein, the first opening having a removable cover;   (e) the second cavity having a second opening therein, the second opening having a removable cover; and   (f) whereby when the covers are removed the fragrances of first and second volatilities independently exit their respective cavities.   
     
     
       2. The cartridge of claim 1 wherein the second cavity contains a greater volume of fragrance than the first cavity, the first fragrance having first volatility lower than the second volatility of the second fragrance. 
     
     
       3. The cartridge of claim 1 wherein the first cavity is sized and configured to generally rest on the second cavity, the second cavity sized and configured to support the first cavity. 
     
     
       4. The cartridge of claim 1 wherein the first opening is generally larger than the second opening, thereby allowing greater exposure of the fragrance of lower volatility and less exposure of the fragrance of higher volatility, whereby when the removable covers are removed the fragrances within the first and second cavities may independently exit their respective cavities thereby equalizing the rate of evaporation of the fragrances. 
     
     
       5. The cartridge of claim 1 wherein the second opening is sized, in relation to the first opening, so that the rates of evaporation of the first and second fragrances are controlled, thereby causing the fragrances to expire at approximately the same time. 
     
     
       6. The cartridge of claim 1 wherein the housing forms a single integral unit containing the first and second fragrances whereby when the covers are removed and the unit is inserted into an air freshener device, the unit allows independent exiting of the first and second fragrances. 
     
     
       7. The cartridge of claim 1, wherein the cover for the first opening is separate from the cover for the second opening. 
     
     
       8. A cartridge for an air freshener device, comprising: (a) a housing having a sealed first cavity and a sealed cavity, the first cavity sized and configured to generally rest on the second cavity, the second cavity sized and configured to support the first cavity;   (b) a first fragrance located within the first cavity, the first fragrance having a first volatility;   (c) a second fragrance located within the second cavity, the second fragrance having a second volatility, wherein the second cavity contains a greater volume of fragrance than the first cavity, the first volatility lower than the second volatility;   (d) the first cavity having a first opening therein, the first opening having a removable cover;   (e) the second cavity having a second opening therein, the second opening having a removable cover, wherein the first opening is generally larger than the second opening, thereby allowing greater exposure of the fragrance of lower volatility and less exposure of the fragrance of higher volatility, whereby when the removable covers are removed, the fragrances within the first and second cavities may independently exit their respective cavities thereby equalizing the rate of evaporation of the fragrances.   
     
     
       9. The cartridge of claim 8 wherein the rates of evaporation of the first and second fragrances are controlled, thereby causing the fragrances to expire at approximately the same time. 
     
     
       10. The cartridge of claim 8 wherein the housing forms a single integral unit containing the first and second fragrances whereby when the cover is removed and the unit is inserted into the air freshener device the unit allows independent exiting of the first and second fragrances. 
     
     
       11. The cartridge of claim 8, wherein the cover for the first opening is separate from the cover for the second opening.
